Heat source pumps can be used for both space heating and domestic hot water, depending on the type of air source heat pump. You can also use it to heat water, depending on the water temperature (also known as "flow temperature") in the heating system. To be able to heat water, the flow temperature needs to be around 55℃, while the airflow temperature will be 35℃ if your system is only designed for space heating.
Heat source pumps can work even at lower temperatures. Air source heat pumps can extract heat from the environment air, making them highly efficient even at low temperatures.
Heat source pump has high seasonal performance coefficient (SCOP), which means they are efficient in both winter and summer due to their outstanding SCOP. The efficiency of a heat pump is measured by comparing the input power required to generate heat with the output heat, and the "seasonal COP" is adjusted according to the seasons.
Heat source pump installation can be powered by wind or solar energy. Air source heat pumps can be powered by wind or solar energy (using solar panels) instead of the grid. Most heat pumps are considered semi-renewable as the operational systems still require electricity. However, combining heat pumps with solar panels can make them more sustainable.
Air source heat pumps have a long life span, and they can run for up to 20 years with proper maintenance. Additionally, most air source heat pumps have a five-year warranty. Unlike fuel boilers, air source heat pumps do not require storing fuel as the fuel used is external air. Using fuel, such as oil or wood chips, requires you to store the oil somewhere, taking up additional space on your property. Not relying on fuel also means you don't have to pay extra for fuel delivery.
Installing a heat pump is easy and takes only two days. It's easier to install than geothermal heat pumps since there's no digging involved. Air source heat pumps usually don't require any planning permission, but it's recommended to check before starting the process. They're great options for both retrofitting and new builds.
It's recommended that a technician performs maintenance and repair of the heat source pump once a year. You can do things like cleaning filters and checking for system leaks and refrigerant levels, removing leaves and dust from the heat pump, and more, to ensure the optimal performance of your heat pump. Any more technical tasks should only be performed by certified installation personnel.
